处理用户条件

运行 Node.js 时，可以使用 --conditions 标志添加自定义用户条件：

node --conditions=development index.js

然后将解析包导入和导出中的 "development" 条件，同时根据需要解析现有的 "node"、"node-addons"、"default"、"import" 和 "require" 条件。

可以使用重复标志设置任意数量的自定义条件。

When running Node.js, custom user conditions can be added with the --conditions flag:

node --conditions=development index.js

which would then resolve the "development" condition in package imports and exports, while resolving the existing "node", "node-addons", "default", "import", and "require" conditions as appropriate.

Any number of custom conditions can be set with repeat flags.
